Fort Sumter is a sea fort built on an artificial island near Charleston, South Carolina, to defend the region from a naval invasion. It was built after British forces captured and occupied Washington during the War of 1812 via a naval attack. The fort was still incomplete in 1861 when the Battle of Fort Sumter occurred from April 12 to 13, sparking the American Civil War. It was severely damaged during the battle and left in ruins. Although there were some efforts at reconstruction after the war, the fort as conceived was never completed. Since the middle of the 20th century, Fort Sumter has been open to the public as part of the Fort Sumter and Fort Moultrie National Historical Park, operated by the National Park Service.
Portland Harbour is beside the Isle of Portland, Dorset, on the south coast of England. Construction of the harbour began in 1849; when completed in 1872, its 520-hectare (1,300-acre) surface area made it the largest human-made harbour in the world, and it remains one of the largest in the world today. It is naturally sheltered by Portland to the south, Chesil Beach to the west and mainland Dorset to the north. It consists of four breakwaters: two southern and two northern. These have a total length of 4.57 km (2.84 mi) and enclose approximately 1,000 ha of water.
Fort Blockhouse is a former military establishment in Gosport, Hampshire, England, and the final version of a complicated site.

As HMS Dolphin, the fort was for most of the 20th century the home of the Royal Navy Submarine Service. It is unique in that it was built over five centuries from its original construction as a blockhouse in 1431 to the final addition of submarine base structures in the mid-1960s.

Fort Hubberstone, on the west side of Milford Haven, Pembrokeshire, is a Grade II* Listed Building which belongs to a series of forts built as part of the inner line of defence of the Haven following the Royal Commission on the Defence of the United Kingdom. Together with Popton Fort on the opposite shore, it provided an interlocking field of fire, and represented the last layer of defence before reaching the Royal Naval dockyard at Pembroke Dock. Construction began in 1860 and was completed in 1863 at a cost of £55,000. It is a large battery, with eleven guns in casemates, eight in an open battery above, with another nine in an open flank battery, and a large barracks to the rear. It is a D-shaped structure, with a bomb-proof roof which protected the barracks and other buildings from mortar projectiles. On its landward side, it was protected by a deep ditch, and on the seaward side by a counter-scarp gallery. The associated casemate battery is located further down the headland and separated from the fort.
Fort Gilkicker is a historic Palmerston fort built at the eastern end of Stokes Bay, Gosport, Hampshire England to dominate the key anchorage of Spithead. It was erected between 1863 and 1871 as a semi-circular arc with 22 casemates, to be armed with five twelve-inch guns, seventeen ten-inch guns and five nine-inch guns. The actual installed armament rather differed from this. In 1902 the RML guns were replaced by two 9.2-inch and two six-inch BL guns, and before the First World War the walls were further strengthened with substantial earthwork embankments. The fort was disarmed in 1956 and used for storage until 1999. On 28th July 2022, the fort was sold at auction for just under £1.4M and planning has been granted for 26 homes. Since then a massive restoration project has been underway.
